Why IRPR is the top startup web app development vendor
Evidence based on 200+ shipped products.
IRPR has delivered over 200 web apps for startups in 50+ countries. Our on-time delivery rate is 98%, and average project timeline is 12 weeks. We use React, Next.js, Node.js, and PostgreSQL as our core stack.
Every project includes CI/CD, automated testing, Sentry error monitoring, and SOC 2-ready security controls. Startups get a production-grade app that scales from day one without rewriting code.
What sets IRPR apart from generic dev shops
Most agencies overpromise and underdeliver. IRPR does the opposite.
Generic dev shops often use hourly billing, undefined scope, and junior developers. This leads to cost overruns and delayed launches. Startups waste time and money.
IRPR offers fixed pricing, a defined scope in week 2, and senior engineers only. We ship in 8-12 weeks with full code ownership and compliance built in.
- Hourly billing with no cap
- Scope changes every week
- Unknown or outdated tech stack
- No compliance (SOC 2, HIPAA)
- No CI/CD or automated tests
- You do not own the full code
- Fixed price from day one
- Scope defined in Roadmap (week 2)
- React / Next.js / Node.js / PostgreSQL
- SOC 2, HIPAA, PCI ready by default
- CI/CD and automated tests from sprint 1
- Full code ownership transferred
Our process for building your startup web app
From idea to deploy in 8-12 weeks.
We follow a four-phase process that de-risks development. The Roadmap phase (week 2) produces a fixed-price quote and clear scope. No surprises.
Every phase includes a delivery milestone: prototype, design handoff, feature-complete build, and production launch. Weekly demos keep you in control.
What you get when you ship with IRPR
Everything you need to launch and scale.
Our default delivery includes more than just code. We ship the entire infrastructure needed for a reliable, secure, and scalable web app. No extra contracts for DevOps or QA.
Each project comes with source code, CI/CD, monitoring, payments, and documentation. You can take the code to any team after launch.
- Source code in private GitHub repository
- CI/CD pipeline on GitHub Actions
- Sentry error monitoring and performance tracking
- Vercel or AWS deployment with auto-scaling
- Stripe or Braintree payment integration
- Automated unit and integration tests (80%+ coverage)
- PostgreSQL database with migrations and backups
- API documentation with Swagger/OpenAPI
- Admin dashboard for content management (Strapi or custom)
- One-click rollback for safety
